7 To all whom it may concern:

Be it known that I, RICHARD F. HOMMEL,

a citizen of the United States, residing in the cityand county of San Francisco and State of California, have invented a new and useful Improvement in Automatic Parachute Attachments for 'Aeroplanes, of which the following is-a specification.

My invention relates to parachutes for aeroplanes that will be automatically pro jected into a supporting position as soon as released and its object is to prevent the too rapid falling of an aeroplane in cases of emergency, such as when'the motor is dis- 1-5 abled or for any purpose fails to operate.

A full and clear comprehension of my invention may be had by reference to the drawings forming a part of this specification wherein like numerals of reference designate'similar parts throughout the said specification and drawings and in which- Flgure 1 1s a broken plan view of an aeroplane composed of circular or cylindrical gas bags of stiff material connected by a central web, one of the said bags being disclosed in the figure, and one of the wings of the parachute beingdisclosed in anextended position. Fig. 2 is a vertical transverse sectional view disclosing my parachute attached thereto in a fdlded position, the dotted lines indicating the extended position of one ofthe parachute wings.

My invention consists of folded canvases having their outer edges secured to the outer 85 ends of supporting poles which are secured within suitable channels within the gas planes. The inner edges of the canvases are secured to the gas bags so thatwhenthe poles are automatically projected the canvases will be extended from the sides of the aeroplane bagsin a supporting position Referring to the drawings the numeral 1 is used to designate the gas bags of an aeroplane which are connected by means of the central web 2 which is hollow and filled with gas. Withinsuitable channels 3, situ-- ated transversely to the aeroplane or bags 1, are the poles 4 having collars 4 secured thereto. Betweenv the collars 4 and the W closed ends of the channels 3 the springs 5 are interposed. A lug 6on the outer ends of the poles, is retained against the tension of the'sprin'gs. 5 by means of the latch 7 which is secured to the gas bag 1. T ese 15E latches may be released by ineans of the secured to the outer ends of the poles 4.

"within the channels against'the tension of lines 8 which extend from the said latches 7 to any suitable portion of the aeroplane Where they will be within reach of the operator.- Canvases or Wings 9 are folded 4 against the sides of the gas bags 1 and under a shelf 10 secured to the said bag 1. 1 The inner ends of the said canvases are secured to the sides of the gas bags 1 while the outer edges of the said canvases 9 are '65 When it is desired to release the wings 9 'the same is accomplished by releasing the latches 7 by means of the'lines 8 As soon-- as the latchesare pulled from the lugs 6 on the poles 4 the springs 5 project the poles 4 to the position indicated in Fig. l of the drawings in full lines or tothe position in-. dicated by. dotted lines in Fig. 2 of the drawings. As the poles at are projected into position the wings 9 are likewise projected into the positions indicated in full lines in Fig. 1 of the drawings and in F igrQ the extended'position of the wings 9 is indicated in dotted lines v It is obvious from the foregoing that I 30 have provided means for automatically projecting parachute wings into a supporting positionrfrom the sides of the aeroplane. V Having thus described my invention what I claim as new and desire to secure by Letters'Patent is-' l 1.;An automatic parachute attachment for aeroplanes comprising a plurality of v transversely exten ding channels having one end closed, transverse poles secured within the said channels; collars secured to the poles; springs interposed between the collars-on the poles and the closed ends of the. channels; 'means for retaining the poles the springs; canvas wings folded and 'secured against the sides of the aeroplanes,

the outer edges of the canvaswings vbeing secured to the outerendspf the poles; and means for releasing the poles from "the channels A 2. In an automatic parachute attachment for aeroplanes the combination 1 with an aeroplane'body of suitabletransverse chan nels therein having one end vo osed'; poles within the channels; collars secured to the poles; springs inter osed within the channels and between th collars on the'poles and the closed ends ofthe cha nelsg, lugs on the outer ends of the poles; lath secured to '11} the aeroplane and adapted to engage the means for releasing the latches from the lugs lugs on the poles; horizontal extensions seon the poles. I

cured to the aeroplane slightly above the In witness whereof I hereunto set my sigtransverse channels therein; canvas wings nature in the presence of two subscribing folded against'the sides of and having their witnesses. inner edges secured "to the aeroplane body below the horizontal extensions and above v the opening of the channels therein and the 'Witnesses: outer edges of'the said wings being eon- H, S. BODLEY, 10 nected to the outer ends of the poles; and R. S. BROWNE.
